Left and center columns from one subject with hypertensive retinopathy; right column from one subject with CRVO. Left column shows AOSLO FA images of a fusiform MA with stable boundaries at four different imaging sessions over a 4-month period. Center column follows a mixed MA with growth between time 0 (perimeter: 162 μm, area: 1702 μm², feret max: 52 μm, feret min: 57 μm) and a second imaging session at 4 months (perimeter: 230 μm, area: 3676 μm², feret max: 63 μm, feret min: 77 μm). The initial image shows a focal bulge MA in the upper right corner that appears to have regressed by the later session. Right column depicts a region with saccular (perimeter: 145 μm, area 1415 μm², feret max: 52 μm, feret min: 39 μm) and mixed MAs (perimeter: 120 μm, area 1030 μm², feret max: 40 μm, feret min: 35 μm) imaged before and after anti-VEGF treatment (asterisk indicates treatment had occurred 3 weeks prior). The mixed MA regressed and continued to be hypofluorescent at an additional follow-up imaging session while the saccular MA remained stable. Scale bar: 100 μm. ND, no data.
